TOPCAT and Gaia

TOPCAT, and its command line counterpart STILTS, are powerful tools for working with large source catalogues. ESA's Gaia mission, most recently with its second data release, is producing source catalogues of unprecedented quality for more than a billion sources. This paper presents some examples of how TOPCAT and STILTS can be used for analysis of Gaia data.Comment: 4 pages, 2 figures; to appear in the Proceedings of ADASS 2018, Astronomical Society of the Pacific (ASP) Conference Serie
